M16 Eagle Nebula

I was able to capture guided 2 minute images of the Eagle Nebula tonight. Here's the results.

Just a note the dark "spire" in the middle of the photo is the "Pillars of Creation".

NGC6826 The Blinking Nebula

Finally had some clear skys tonight, so had a chance to fine tune the alignment of the mount to the new pier. Figured I would give it a quick test. Found the Blinking Nebula and snapped of 15 mins of images.




From Wikipedia:

NGC 6826 is a planetary nebula located in the constellation Cygnus. It is commonly referred to as the "blinking planetary", although many other nebulae can exhibit such "blinking". When viewed through a small telescope, the brightness of the central star overwhelms the eye when viewed directly, obscuring the surrounding nebula. However, it can be viewed well in the peripheral vision (averted vision), which causes it to "blink" in and out of view as the observer's eye wanders.
A distinctive feature of this nebula are the two bright patches on either side, which are known as FLIERs, or Fast Low-Ionization Emission Regions. They appear to be relatively young, and moving outwards at supersonic speeds. According to Bruce Balick (University of Washington), "some of their observed characteristics suggest that they are like sparks flung outward from the central star late in the very recent past (a thousand years ago). Yet their shapes ... seem to suggest that they are stationary, and that material ejected from the star flows past them, scraping gas from their surfaces. Future Hubble observations will monitor any changes in the positions of FLIERs to resolve this issue. In either case, the formation of FLIERs cannot be easily explained by any models of stellar evolution.

M65

While I was out doing some 'testing' of the software and mount I decided to try to image something. I was on the "other side' of the meridian  (I normally shoot everything on the east side) and just picked something bright.
Here's my 1st attempt at M65. (only 5 images stacked / 30 seconds each).
